–Experience in speedy implementation– Since 2006, working with FAO in adopting new concepts

and practices in modernizing irrigation management–Capacity building

KNNL-OBJECTIVES

• Issuing bonds to access funds from the market based on time bound investment plan

• Timely completion of projects

• Better management and speedy decision making process to bring about efficiency in construction and administration of projects.

INSTITUTIONAL REFORMS• Outsourcing of survey, investigation, preparation of

estimates and detailed tender paper to consultants.• E procurement for entrustment of works• Entrustment of works on turnkey / EPC basis• Third party inspection for ensuring quality. • Dedicated/ Project specific field offices.• Use of facilities like tele-call conference/web conference

for day to day monitoring of project works• Training of engineers in irrigation management• Promoting Coaching culture in the Organization• Separate Cadre for KNNL/WRD

YETTINAHOLE PROJECT• A Scheme for diversion of flood water from

west flowing streams in the upper reaches of western ghats near Sakleshpura to provide drinking water to drought prone areas of Tumkur, Bangalore rural, Ramnagara, Kolar & Chikkaballapura districts (East)

CHALLENGES IN HARNESSING

WEST FLOWING STREAMS

12

It is difficult to harness water available in Western Ghats due to

Environmental constraints owing to Presence of Western Ghats.Engineering challengesEconomic viability

Hence, an effort has been made to divert only a meager percentage of water that too from the upper reaches of the Western Ghats close to the plateau.

YETTINAHOLE SCHEME AT A GLANCE

• The streams that have been proposed to be harnessed are listed

below. 1. Yettinahole 6. Yettinahole lower

reach 2. Yettinahole Tributary-1 7. Kerihole 3. Yettinahole Tributary-2 8. Hongadahalla hole 4. Kadumane hole – 1 5. Kadumane hole - 2

YETTINAHOLE SCHEME AT A GLANCE

Extent of Watershed Area in Western Ghats of Karnataka – 24,530 Km2

Available Catchments – 13 Present Scheme considers tapping streams which are originating from upper

reaches of Western Ghats near Sakleshpur having an elevation above 730 m.

It is clear from the above schematic representation that a meager percentage of water is being planned to be diverted from West to East for the purpose of meeting the drinking water requirement in the drought prone areas in the present scheme.

YETTINAHOLE SCHEME AT A GLANCE

The present scheme envisages :-

• Simple diversion structures across the stream keeping the maximum

water level restricted within the flanks of the streams.

• A suitable intake structure and lifting arrangements on the foreshores

in order to lift the water only during peak monsoon / floods.

• Dedicated raising main (pipes) buried under the ground to convey

lifted water from the pump house.

15

YETTINAHOLE SCHEME AT A GLANCE

• The pipeline will be routed parallel to existing corridors in order to minimize the

opening of the new corridors.

• The Raising mains will be taken from the intake structure up to Haravanahalli

near Sakleshpura beyond which it is planned to have a gravity canal (250 km)

to convey the water up to Tumkur.

• The alignment of the canal has been planned along the ridge line bifurcating

the Cauvery and Krishna basins.

• A raising main for a length of 8.1 km has been planned to convey the water to

a storage Reservoir, near Devarayanadurga, with a capacity of about 10 TMC.16

YETTINAHOLE SCHEME AT A GLANCE

• From the reservoir two raising mains have been proposed one towards

Chikkaballapura (88.2 km) and other towards Kolar (55.9 km) to provide

drinking water needs and filling of 198 and 139 MI/ZP Tanks respectively in

the above Districts.

Cost

• Based on the line estimate, the Government of Karnataka has accorded

Administrative approval vide GO No ಜಸಂಒ 203 ವಿಭ್ರಾಇ 2012

dated:13.07.2012 - costing about Rs.8323.50 crores for diverting about

24.01 TMC of water.17

YETTINAHOLE PROJECT

UN-FAO PROPOSAL FOR THE CENTRE OF EXCELLENCE IN INDIA:

Key issues ;• improving water governance at the level of irrigation systems and

river basins, as well a ground water and trans boundary levels;• adopting a multi-sectoral strategic planning and management

approach to revision of food security, agriculture, water and environment policies and investment strategies;

• adopting demand driven and service oriented irrigation development and management strategies;

• modernising irrigation systems;• enhancing water productivity for both rain-fed and irrigated

production;• enhancing environmental protection; and• focusing on agro-ecosystems and populations particularly at risk, such

as in tropical deltas and in arid or semi-arid areas.
